'Be itnknown' that I, Cn sTER BRAD ORD, acitizen o f'the United States, residing at Indiana olis, in the countyof Marion and State of 'ana, have im ented certain new and useful lnrov'ements in Swinging-Conveyers, offwhich the following is a s)ecifioation. In the class of dev ces w ich are attached to'threshingmachines to receive the threshed 'grain'from these arator, elevate andweigh thesame, and de i'ver it to stacks or wagons for ther disposition,two distinct varieties of the grain' delivering: or transferring device'-';,con'1.m onl known as a Fcross conveyer are is employe .Oneis thewell irnown stationv ary?icross conveyor which is mounted upon the deckof the separator-and remains con: tinuously'in the position whereplaced.

describedlfor the purpose of pro'vidingroom "vention', and thereforewill not. be described herein exceptincidentallyin describingmhe Thec'onveyer proper has the usual aiiger shaft 21 and worm or auger .22,said shaft .being mounted, in sui-tablebea rings in the ends or heads ofthe tube or casin -23 which forms the principal part of"th e shell ofthe convey-er. Said conveyer is provided at its discharging end with adischarging mouth i 24; and its opposite end develops into 'a mi ceivmgmouth having an end inclined walk 25, and to the uppenedg'e of thismouth (whichic onstitutes the lower part of the receiving hopper)the'upper portion 26 of said, hopper is scured'this portion beinglocated .directlybelow the weigher W, or thedischarging ,ii outh of theelevator, (according to the? variety of 1- nachine with which theconi'ey'er is used) and is adapted to receive the grain. I The wall 25is inclined (as shown and just forthe peculiar arrangement of drivinggears which have devised. It also faclhtates the flow of thefgrain tothe auger, and en ables't-he eonveyer toclean itself more thoroughly inoperation." To the outer and under side 'of this inclined'wall issecured a bearing .31 .for the {shaft 21. In the same structure'is alsoa socket to receive the pivot shaft 32. Said ivot shaft is lprox ided onits lower end wit a bearing-plate 3.3 which rests in asiiitablecavity inthe hracke-tmemhers 3 t. The bearing surface on the part- 33 ispreferably of the form ofa zone on a lobe,

the center of which is coincident with the center of'the gear trav elion the ivot shaft, as will bepres'ently. descrl ed,'am the correspondingsurface onthe part- ?A is similarly formed. I This permitso the slighto'scillation desirable to a support of this cheraoter, without causingan of the parts,to;' 'bind.

The supporting bracket is 1 shojiinfas'fforn ed in two pa-rts 34 and 35,the' par't 35" be i i1g., fitted toone leg'of the elevator E and being Yclam ed thereon by clamping.Qbandsjfifi. The rackethowei'er .nii ht bemadam 5 singl iepe dfisir l the" ead arts are assemble secured to they}:(1

. a shown 'in the' form'fof a s'litted pla enga es with the upper sideof a corresponding d ouble bevel gear 42 which is mounted loosely on thepivot shaft 32. The under side of said doublebevel gear 42 engages witha bevel gear 43 which is mounted on the driving shaft 44, said drivingshaft being mounted in suitable bearings secured to able bearings in abracket 51 which is ad 'justably mounted on the other leg of theelevator from that on which the bracket 34-35 is mounted and is securedthereto bysuitable clamping rings (or rather half-rings) I 52. Saidbracket is adjustable on said vator leg both circumferentially andlongitudinally, and is thus capable of being admated to [the exactposition desired. The

, earings 53 for said countershaft 45 are also adjustably mounted in thebracket, being supported upon one side by projecting oints 54" whichenter suitable cavit1esin t e ad'- 'acent sides of Tsaidbearings, sothat said earings' are capable of shding' somewhat thereon, and upon theother side by means of set-screws 55, the points of which entercavitiesin the opposite side of said bearing.

Said set-screws are also provided with jam" nuts 56 by means of whichthey'may be securely locked in adjustable position, Said "bearings'arethus rendered self-adjustable,

so that. they will line u properly with the shaft automatically. hecountershaft is. shown as alsodriving the main upper elevator shaft 61by means of a s rocket chain 62 running over suitable sproc et'wheels'63' a belt 65 and 64,. and as being driven 'bIy e separator fromsomesuitable pulley on t (notshown).

The bracket'34+35, like the bracket 51,

'is-adgustable on the elevator. leg both circum erentially andlongitudinally, and the conveyor may thus. bebrought to the exactposition desired. The outer portion of. the 1clongeperis sup f'orted.froml the elevator y "a suita'le and preferably flexible 'su ort 71running from a pointsubstam (where it is shown as connects to saidheadby ja'bracket 72) over the end of a strut 73 to a bandsurroundingthe tube .or casing 23! or weigher'fa down theinclined wall 25 follows:e figain comingfrom the elevator into the hopper 26 and slides throughwhich, the auger-22 conveys it rap idly to the discharging per-iscircular. in are: so that it're'ceives y perpendicular above the pivotshaft 32 into the tube 23 month 24. The 'hkolp;

The an or shaft 21 isdriven in any positionby t e gears which have been described from .anysuitable source of power-usually the countershaft 45. By

reason of the peculiar form of the conveyor end these gears are enabledto be of substan tial size and pro ortions and to be located centrallybelow t e hopper and receiving end of the conveyer. As will be obvious,"the gears perr'nit the swingin of the conveyor to any position desired,eit er across the separator, or extending out therefrom, and to be sopositioned as to be able to deliver into a sired.
